HEAT ATTACHMENT FOB. GAS-JETS.

Specificationof Letters Patent.

Patented July 3, 191W.

Application filed January 29, 1917. Serial No. 145,094.

To all whom it may concern: 'Be it known that I, GUY IV. FnnDoN, a citizen 'of the United States, residing at Cresskill, county of Bergen, State of New Jersey, have invented certain new and useful Improvements in Heater Attachments for Gaswlets; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to. which it appertains to make and use the same.

My invention relates to heater attach ments for gas jets, and comprises a device adapted to be slipped over or placed upon the ordinary gas bracket or chandelier for the purpose of reflecting the heat and light developed by the combustion of the gas in the burner downward into the room or space below the jet.

My device is also provided with means whereby a kettle or other receptacle may be placed uponsaid device for the purpose of heating or cooking.

My device is especially designed for use as a temporary and portable device tobe used either for cooking or heating. It may be readily detached and carried by a traveler in his suit case, being more especially made in knock-clown form.

In the drawings:

Figure 1 is a top view of my device.

Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 2 is a view showing ainodified form of my supporting disk and rod.

Fig. 3 is a. perspective of my pivot or central disk and sleeve; and I Fig. 4 is a section showing a modification.

In my device I provideadisk 1, upon the central upper part of which are a number of ribs or other projections2; a cooking or other receptacle 3 may be supported upon said ribs or projections. The disk is provided toward its edge with an outwardly and downwardly extended curve 4, a perpendicularcentral Zone 5, and a further curve 6. In the central zone I provide a number o f openings 7. My sleeve 8, which is supported upon the pillar 9 of the gas jet, is made slightly conical in form, as-

shown in Fig. 2, so as to better fit the said pillar, and integral with it and made from the same piece of metal is a lower disk 10, which terminates in an outward and upward extending curve 11.

In the bottom of this disk I provide certain openings 12, corresponding in number and spacing with the openings 7 in the plate above mentioned. I provide a number of rigid spacing rods or wires 13 to connect said disk and plate. One of these wires is passed through a hole 12 in the disk and bent around the curved upper part of said disk; it then extends upward and outward, and at its upper end is made to pass through a hole 7 in the perpendicular.zone mentioned, and its end is then bent downward and outward into rigid contact with the lower curved surface 6. In fact. I prefer to bend this out and down with such force that the outer end 14 of the wire bites into or makes a depression in the surface of the plate around the curve 6, indicated in Fig. 4, where I have lettered said depression by they sign 15. The lower end, which enters the hole 12, is bent over so as to allow little play, and the upper end being bent over and biting into the curved surface 6, I am enabled. to produce an eXceedingly rigid structure, which is simple to manufacture, does not get out of order, and is practically indestructible and fool proof. I may use any number of these supporting rods 13. three or four being usually a sufli' cient number.

On the upper inner surface of my plate I provide a light reflecting lining 16, inclicated in Fig. 2, and here shown to be made of asbestos. This lining extends down practically as far as the perpendicular zone before mentioned, and is usually and preferably made of asbestos, whereby the light and heat of the gas jet below this lining are both reflected downward into the room. I secure this lining in place by any suitable fastening means. as the rivets 17, the bolt and nut 18, or, as shown in Fig. 4, a short nail or rivet 19 driven through the plate or the hole in the plate and held there by friction merely. The advantage of this construction, as well. as of the bolt and nut indicated at 18, is that they may be removed with ease and a new asbestos lining put on in case the previous one becomes smoked or torn.

I have shown in Fig. 2 a somewhat modified construction in which the disk 1O isat the upper part of the sleeve 8, and in which the curves of the supporting rod 13 are reversed or modified.

It is apparent that the weight of disk 1 and that of any receptacle on said disk is supported and carried by the rods 13 and their engagement with the holes 7. The weight is taken by these rods at the outside of the curve at the upper curved end and transferred to the sleeve upon the gas pillar and thence to the gas bracket.

I arrange the fastening devices 17 for the asbestos so as to come between the ribs 2, as before mentioned. This insures an even bottom for the support of any vessel.

The operation and method of using my device is apparent on inspection. Each succeeding pair of wires or rods 13 constitute with the upper plate substantially a triangle, since the lower disk is of comparatively small diameter, and this triangular structure, together with the close connection of the upper ends of rods 13 with the curve 6,

enables me to make a very strong and rigidly braced device.

While the wires or rods 13 afiord extreme rigidity to my structure, they are so small comparatively in diameter, that they do not materially interfere with the passage of light either from the jet or from the reflcctor.

The upper plate acts as a bufier or protector, preventing a gas jet being turned by acareless person to contact with a door or other woodwork, or burnable surface, or to smoke the wall.

While my device is rigid in structure and permanent in form, it may be taken apart easily by upbending one or two of the upper ends of the wires 13 and slipping the upper loop through a hole 7. If but three wires are used, it will be necessary, usually,to do this to but one of the supporting wires, whereby the other two may be removed by tilting the plate. It four wires are used, it is necessary to bend up the ends of two supporting wires. 7 I desire to cover all equivalents.

. Having thus described my invention, what I claim and desire to secure by Letters Patent-of the United States, is:

. 1. A heater attachment for gas jets comprising a plate provided with a down-turned edge having holes therethrough, a sleeve adapted to fit upon the pillar of a gas jet, said sleeve beingprovided at its base with an integral disk, saiddisk terminating in a rounded up-curved edge, said disk having holes corresponding in number and'spacing to the holes in the said plate, and rigid supports extending from said disk to said plate, said supports being passed through said disk holes and curved about said up-turned edge and passed through and bent down into contact with said down-turned edge, to make a rigid structure.

'2. A heater attachment for gas jets comprising a plate provided with holes through it near its edge, a sleeve adapted to fit upon the pillar'of a gas jet, a disk integral with said sleeve, said disk terminating in a rounded curved edge and provided with holes therethrough near said edge, and stiff supporting rods passed through said last named holes and curved about saidcurved edge, said rods extending up to said plate, passed through the holes thereof, and bent down upon said plate.
